Question

Simplify: (6x2 - 3 + 5x3) - (4x3 - 2x2 - 16)

Answer 1

I'm going to assume that the numbers after the x are exponents. Correct?

Answer 2

Yes.

Answer 3

Do you know how to distribute the minus sign in the middle?

Answer 4

Start by reordering the first polynomial starting with the highest order term

Answer 5

Then multiply -1 by each terms inside the parentheses

Answer 6

x3 + 8x2 + 13 is what i am getting.

Answer 7

Yeah correct

Answer 8

I combined like terms and then arranged the completed terms by highest order, is that correct

Answer 9

Yes

Answer 10

You should get -5x3+6x2-3-4x3-2x2-16)
Then you subtract 4x3 from -5x3 to get -9x3
So -9x3+6x3-3+2x2+16
Add 6x2 and 2x2 to get 8x2
Now the problem looks like -9x3+8x2-3+16
There's one more step after this. Do you know what it is?

Answer 11

Where did the negative 5x^3 come from? You're only supposed to distribute the negative sign to the expression on the right side. BasedGod1122 was correct.

Answer 12

I've got another one for you.
Choose the correct simplification of the expression (8x - 5)(2x2 - 5x - 6).

Answer 13

You just distribute.

Answer 14

Multiply 8x to 2x^2, -5x, and -6

Answer 15

That's the first part and you do the same thing with -5

Answer 16

@BasedGod1122 do you have answer choices for your first question because I'm sure the answer is -9x^3+8x^2+13

Answer 17

(6x2 - 3 + 5x3) - (4x3 - 2x2 - 16)
First step: Distribute the negative sign.
6x^2 - 3 +5x^3 - 4x^3 +2x^2 + 16
And then you combine like terms

Answer 18

Arranging the terms is unnecessary until the end

Answer 19

What is your final answer @turquoisee?

Answer 20

It was what BasedGod1122 got

Answer 21

x^3 + 8x^2 + 13

Answer 22

I don't think that's the correct answer but if @basedgod1122 thinks it is then he should go with that

Answer 23

The answer I got was an answer choice, and one of the only remotely plausible ones.

Answer 24

Thanks!

Answer 25

Did you get the second question?

Answer 26

Yes I did, thanks turquoisee

Answer 27

No problem!
